Variable-volume bellows bottle

Abstract

The invention relates to a variable-volume bottle made from PET and having an elastically deformable and plastic-deformation-resistant bellows structure, which allows the volume of the bottle to be adjusted according to the degree to which the peripheral annular folds are folded. The invention comprises one or more sectors without peripheral annular folds, intended for identification labels.

1 - 9 . (canceled) 
     
     
         10 . A variable volume container, made from plastics, for food consumption, comprising: a tubular body having a closed bottom, an upper end having a neck with a mouthpiece, over which a closure plug is adapted; the tubular body having a plurality of peripheral annular folds that are a bellows-type, elastically deformable and plastic-deformation-resistant configuration, and allow a regulation of the volume of the container based on the degree to which the peripheral annular folds are folded. 
     
     
         11 . The container of  claim 10 , wherein the tubular body has one or more sectors that are not affected by the peripheral annular folds, the sectors constituent formal and dimensionally suitable surfaces to receive an identifying label of the product to be contained. 
     
     
         12 . The container of  claim 10 , wherein the tubular body is cylindrical, conical triangular or a polygonal form in the cubic system and/or cylindrical polygonal in the cubic system of curved or angled edge. 
     
     
         13 . The container of  claim 10 , wherein the bellows-type annular folds are symmetric bellows, symmetric or asymmetric flake, spiral bellows. 
     
     
         14 . The container of  claim 10 , wherein the configuration of the below-type annular folds are circular, ellipse, triangular, rectangular, or any regular or irregular polygonal form with curved or angled edge, as well as those resulting from cross sections of conics or figure of revolution and those formed by polar functions or equations and/or the combination of  2  or more of the aforementioned. 
     
     
         15 . The container of  claim 10 , wherein the length of the plane of the bellows ranges between 0.5 cm and 3.5 cm. 
     
     
         16 . The container of  claim 10 , wherein the angle of inclination of the bellows ranges from 10 degrees to 45 degrees. 
     
     
         17 . The container of  claim 10 , wherein there are three points of the body of the bottle, at 120 degrees of separation and attached to the base of the bottle 3 pivots with sealing closure that are introduced in notches of the major planes of the bottle, also at 120 degrees. 
     
     
         18 . The container of  claim 10 , wherein the volume of the container is variable between 100 cm 3  and 5 thousand cm 3 . 
     
     
         19 . The container of  claim 15 , wherein the length of the plane of the bellows is 2.5 cm. 
     
     
         20 . The container of  claim 16 , wherein the angle of inclination of the bellows is 21 degrees 30 minutes.
